To all whom it may concern.

Be it known that I, Dnrmrnios STEReiAN- oPUL'os, a subject of theKingdom of Greece, residing at 765 Courtland avenue, New York city, NewYork, have invented certain new and useful Improvements in .RepeatingRifles, of which the following is a clear, full, and exact description.

The object of this invention is to improve the construction ofrepeat-ing rifles of that class in which the cartridges are heldinarotary magazine within the gun stock, where.l such gun is provided withan ejector mech? anism located along the gun-barrel in front of thetrigger, so t-hat manipulating the gun to load, lire and unload, thegunners hand need never bel moved back of the breech in tiringsuccessive shots, and at the same time maintaining all the importantfeatures of readyloading, which can be se; cured by a vgun provided witha circular magazine wit-hin the stock. To load such a gun, it is onlynecessary to have the cartridges in alinementin the clip, then push theentire series of cartridges. into place within t-he stock'.

My invention further relates to various details of construction andarrangement of' parts as hereinafter setl forth, whereby a simple,cheap, readily assembled, easily constructed and readily cleaned gun canbe secured.

In carrying out the main object of my inn vention, I provide a springpressed rotating drum having recessed sides located in a cylindricalchamber in thegun stock in front ofthe trigger mechanism. The breechcloser and tiring pin mechanism are mounted to slide together backwardand forward across the cylindrical chamber. to close the same at thetop'where the cartridges are inserted. This breech closer and liring pinmechanism is reciprocated back and forth by links passing above andacross the cylindrical chamber, and the links are operated by adepending handle passing through the slotted forestock of the gun.

The scope of my invention will be pointed out in the claims.

As shown in the drawings, 1 is the forestock, in which the gun barrel 2is secured in the ordinary manner, 3 is the. trigger protected by thetrigger guard 4. The trigger is pivoted at in ears secured to a. plate 6fast in 'the gun stock. `Within the trigger compartment of the stock isa doublearmed lever 7 forming part of the trigger, and having pivoted toit at 8 and 9 two upwardly eX- tending pins 10 and 11, passing throughguides in a metal plate 12 secured on' the upper surface. of the gunstock. These pins upon pulling the trigger are moved, the pin 10downwardly and the pin l1 upwardly, one unlatching the tiring pin barrel13, the second unlocking the latch 14, that a spring 15 within thefiring pin barrel 13 may roject the firing pin 16 against the cartridge.At the rear of the rifle barrel the breech is formed as indicated inFigs. 10 and 11. At this point the rifle barrel is provided withrecesses 17 and 18, the material of the barrel forming shoulders to therear of the recesses. Between the recesses the ride barrel-is open sothat the breech block 19 may be inserted into the breech with the breechlocking blocks 20 in position to be rotated into'a position to be lockedbehind the shoulders just referred to. 'Io secure this rotation of thebreech block 19 it is provided with a sleeve 20a fitting into the firingpin barrel 13. The sleeve 20a is formed with a helical groove 21 andWith a reduced portion 22. In the-helical groove 21 there is a block 23fast to the firing pin barrel, so that upon a forward movement of thefiring pin barrel and a stoppage of the breech block, the block will .beforced into the pin barrel, and at the same time rotated to lock thebreech. In the annular recess 22 a lug 24 on a jaw 25 is located. Thejaw 25 consists of a jaw properv 26 which 'is turned over the breech'block to engage the base and groove of a cartridge for the purposeshereinafter to be described. An arm 27, part of the jaw member,'extendsto the rear of the block 24, and is limited in its rearward movement bya pin 28 in the irin pin barrel.

The face o? the breech block has a depressed portion 28 which isnormally engaged by a`turned-over end 29 of aslide arm 30, but which isthrown forward upon'the retraction of the firing pin barrel 13 by'reason of its end striking against an upwardly spring pressed pawl 31fast to the'v gun stock so that the cartridge may be ejected.

Wings or projections 32 ateach side of the firing pin barrel 13 areengaged by hooked ends"33 of long links 34 which pass through themagazine above and to. one side of the cartridges. The'links 34 meetwithin a longitudinal slot 35 on the gun stock forward 'of the magazine,one link being pivotally fastened by 'a hinge 36 to-a plate 37 to whichis pivoted a handle 38. The handle 38 has a spring pressed latch 39 witha lhooked end 40 adapted to engage a notch 41 vin the plate 37 to keepthe same yrigid for the hands grasp while shooting but at other timesthe latch 39 may beunhooked and the handle .swung out of way into theslot 35.

' The firing pin 16 has a shank 42 on'which is mounted a sleeve 43having a depending lip 44 and a pivoted latch 14. A set nut 45 holds thesleeve in place and serves to adjust-the firing pin 16 in its ringposition.`

The latch 14 is provided with a cylindrical lug 46. fitting a bearing inthe sleeve 43 and is recessed at 47 for a spring 48 tending to throw thelatch 14 into the position of Fig. 10. The firing pin barrel is slottedat its end to permit the ent-rance of the-latch 14 and lip 44 into thefiring pin barrel, but

Wings 494.49 at thesides of the latch 14 are adapted to hold the latchin the position of Fig. 10 until elevatedby the pin 11 to aline withproperly recessed portions of the sleeve 43 when the spring will projectthe firing pin. When the trigger 3 is pulled not lonly lis the latch 14liftedthatit may enter the'iring pin barrel but the pin 10 is lowered toallow the lip 44 to move forward. Also, when the pin barrel is withdrawnrearwardly both latch 14 and lip 44 pass freely over the ends of thepins 10 -and11, but upon closing the breech with a forward movement thelip 44 catches against the pin 10 and holds the sleeve 43 back releasingthe wings 49 to cock the gun.

The magazine chamber 50 is closed at the bottom by a plate 51 providedwith up rights 52 carrying a freely rotatable drum 53 having alongitudinally fluted surface to form cradles for the cartridges. Aspring 54 tends to rotate the drum into-the position of Fig. 8. Onelong' lip 55 receives the first cartridge to be inserted. The plate 51has a finger hole 56 through which a slide bar 57 may be moved back andforth. The slide bar 57 carries a pin 58 in its forward end to engage ahole in the forward wall ofthe magazine chamber and two pins 59 at itsother end alined with two pins 60 at the end of "a pivoted arm 61. `Aspring62 normally holds the arm 61 in the position of Fig. 1, so thatupon inserting the plate and drum t-he pins 60 will force the slide barforward, engage the uprights and cause the forward pin to engage thewall of the chamber..

The gun barrel back of the breech is open at the top and to one side(see Figs. 1 and 2, 6 and 8) and the magazine is closedby the firing pinbarrel when `in its forward position. The gun barrel is slotted clearthrough to allow the cartridges to enter the magazine and is providedwith a pair of guide shoulders 63 (Fig. 2) to support and hold one endof a cartridge clip 64 that its cartridges may be quickly and readilyflinserted into the magazine as shown in Fig.- 8. When the gun has beenthus loaded `one cartridge remains above the others as shown in Fig. 6;it may be struck by the breech block and forced into the' rifle boreupon moving the handle 38 forward. A resiliently held plate 65 normallybears against the upper cartridge with s'ufiicient pressure to preventthe ejection of the cartridges in the magazine. A push pin 66, Fig. 3,is provided however to relieve its tension on such cartridge that allcartridges may be expelled if desired. The plate is pivoted at 67 (seeFigs.'6 and 8.)

In using the rifle the cartridges in the clip 64 are inserted as shownin Fig. 8 when .pressure on the topmost cartridge will cause vided forit, Figs. 4 and 11, and stops in` its forward movement; the pin barreleon tinues its forward motion rotating through the stud 23 and helicalgroove 21 the breech block to lock it in position. The gun has beencocked as before described by the lip esami esbeingheld by thepin l0.VElie trigger is then pulled, the tiring pin passes through the blockand strikes the cai dge.` The handle then pulled back, the aws and 29engaging the cartrii'lge groove and the cartridge is extracted into theopen part of the barrel until the endBO of the jaw 25) strikes the pawl3l when that jaw suddenly stops while the other aw still pulling thecartridge back resulting in a quick snappy eideiifise throw of thecartridge -which expels it lfrom the gun. The next cartridge througheffort of the spring pressed drum then comes into a position in front ofthe breech block for a repetition of the operation.

It will be noted that the gun can be loaded by using a clip in anapproved manner andv that all shells may be fired and ejected withouttaking the hand 'from the handle 38 or lowering the -gun from theshoulder. It

-will also be noted that one motion of the handle 38 places thecartridge in position, locks the breech and sets the tiring mechanisin.
